We watch celebrities on TV, listen to them on the radio and see their photos splashed across the pages of magazines…but do we really know what goes on inside the homes of Hollywood families?

One celebrity couple agrees to let Oprah's cameras go where few cameras have gone before. They've never done a television interview together…until now.

He's a Grammy-winning artist who's preparing to launch a new album. She's a supermodel, jewelry designer, television producer and star of Bravo's hit series Project Runway. Seal and his wife, Heidi Klum, have all the credentials of a power couple, but their careers never take top priority.

"I think the key to being a power couple, if there is such a thing, is that you just really have to make sure that you have your priorities right," Seal says. "You have to make sure that your family [comes] first."

This famous family splits its time between Los Angeles, New York, Mexico and Germany, Heidi's birthplace.

"I always wanted to have a big family and a wonderful man, and I totally have that," Heidi says. "But who would have thought that it [would be] Seal! How lucky am I?"
